Summary
Based on studies from eastern Jutland, Denmark,
the ecological demands of 32 species of
Cortinarius subgenus Phlegmacium from deciduous
forests are elucidated. Their presence in
the area is generally restricted to localities with
limestone and where an underlying rich , clayey
soil has been exposed for some decades, typically
along ditches or banks or after landslides along
the coast line . At localities where the wind
has influenced the surface for a long period, the
soil is generally hard with a different mycoflora,
often dominated by species of Russula.
With few exceptions the species of Phlegmacium
in the area seem to have more or less identical
ecological demands. Therefore, many of
them are found growing together, and the rarer
species exclusively occur at localities with a large
total number of species. Rich occurrences of
Phlegmacium species are without exception accompanied
by a high number of other rare and
often less investigated mycorrhizal species of
for example Inocybe and Cortinarius subgenus
Telamonia. Their ecological demands are apparently
similar to those of the Phlegmacium species.
Phlegmacium species are rather conspicuous
and therefore easy to detect. Therefore, they
may be useful as indicators for valuable localities
worthy of protection.
Seven species are reported as new to the Danish
flora, viz.: C. arcuatorum, C. boudieri, C.
claroflavus, C. flavovirens, C. osmophorus, C.
riekenianus & C. rujoolivaceus. Earlier reports
on C. sebaceus are here rejected as being based
on atypical specimens of C. olidus.
